GROUT USED FOR GROUND IMPROVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a grout used for a ground improvement method, excellent in work efficiency, and which has plasticity in the ground.SOLUTION: Provided is the grout comprising: a thickener and a solvent for dissolving the thickener. The grout has viscosity set to 100-5000 mPa.s in accordance with JISZ8803 before injection to the ground, and after injection to the ground, the grout is decomposed in the ground and the viscosity of the grout becomes lower, the grout is used for the ground improvement method. As the thickener, for example, a neutral water soluble polymer such as polyethylene oxide, and as the solvent, for example, water or organic solvent, are used.SELECTED DRAWING: Figure 2
【課題】作業効率に優れ、地盤内で塑性化可能な地盤改良工法に用いる注入剤の提供。【解決手段】増粘剤と増粘剤を溶解させる溶剤とを含有し、地盤への注入前にJISZ8803に準拠して測定された粘度が100〜5000mPa・sに設定され、地盤への注入後に、地盤中で分解されて前記粘性が低下する地盤改良工法に用いられる注入剤。増粘剤としては例えば、ポリエチレンオキサイドのような中性水溶性高分子が、また、溶剤としては例えば、水、有機溶媒が使用される。【選択図】図2
